My favorite version of this trend remains http://alwayshttp.com because https://alwayshttp.com doesn't work since alwayshttp.com:443 doesn't connect.
On the other hand, it's possible to reach https://coffeeshopwifi.com and (with a cloudfront certificate error) https://neverssl.com which makes me wonder if something in whatever I'm using is trying to upgrade to HTTPS when I fail to reach them.

Card networks offer services to receive updated credit card numbers for mutual customers now and have for a bunch of years.
If your credit card expires, many subscription providers will get the updated details automatically.
Here’s an article with some details on the topic: https://www.creditcards.com/credit-card-news/card-updater-se...

While returns are made more complicated by Google and Apple Pay, the card numbers aren’t single-use (which I’m not sure if you mean to imply is the case with google pay today). On both iOS and Android you can view the last few digits of the Device/Virtual Account Number.
I don’t have an Android device to test these instructions on but they seem plausible and corroborated: https://supportcentre.natwestinternational.com/Searchable/91...
When I made a return for an Apple Pay purchase at Target, they saw that the transaction was marked “Tapped” as card type and took my word for which card was correct. Who knows how long that’ll last. Where I really expect to run into problems down the line is when I try to take advantage of the insurance benefits offered by cards and can’t produce an invoice/receipt with the expected card number on it.

Unfortunately (from some perspectives), this isn’t true. Each instance of a card in Apple Pay has a long term Device Account Number (DAN) that functions the same as a physical card’s number (though there is no link between the DAN and actual card number from the merchant’s perspective). The same DAN is used across every transaction. The only way to get a new one (which is pretty easy, relatively speaking) is to unload the card from Apple Pay then re-enroll.

Are you saying that there are zero people that take the MARC commuter rail out of Odenton and transfer to Metro?
People that would (without Metro) have no way of getting from MARC to their DC jobs would disagree with you that Metro it doesn't reduce congestion on 295 and other congested roads that pass through Anne Arundel.

It already does work like this in iOS 11. Apps can present the System photo picker to you and receive only your selected photo while having their Photos access set to "Never".
If you want to try it out install the Wire messenger (if you make the account with a web browser you don't need to provide a phone number), and try to attach a photo but deny Photo library permissions. (Here's the buttons to press: https://imgur.com/a/gc5Iq). Other apps work this way on iOS 11 but this is the one that came to mind.

Five incorrect/bad fingerprint reads will require passcode.

Regardless of SNI the certificate is unencrypted (until TLS 1.3).

Additionally, FPGAs offer better cryptographic algorithm agility than ASICs. With an FPGA you stand a much better chance of being able to upgrade your expensive network hardware with quantum resistant algorithms.

Where would that software auto-update get the decryption key from? If the user has enabled a passcode, then their passcode is used in generation of the key used to protect the disk encryption key.
Even if apple did push an update, the user would still have to unlock their device post-update.

Maryland (at least around Baltimore and DC, in my experience) often feels like a no-region's-land: many Southerners will claim it's the North and Northerners will claim that it's the South. Maryland definitely feels like it's where the lines blur.

In the case of this specific paper from this specific conference, you're in a lot of luck. USENIX put out the full proceedings as a giant PDF, an ePub, and a Mobi ([1]).
If you want to reflow arbitrary pdfs, then you should check out k2pdfopt ([2]). It's how I read academic papers on my Kindle. It does lots of tricks to slice out a useful format from pdfs of many different formats and make them pretty solid on a different screen size.
